On the second-hand gold market, two nearly identical pieces can show two unrelated prices. Variable weights, set stones, hidden margins. Price per gram puts everything back on the same scale.
Every day, we read the prices of eleven online jewelers, convert them to price per gram of 18-karat gold, and line them up next to each other. A ring, a chain, a pendant finally compare in the same language.
How we calculate
We read every product sheet: net weight, purity, set stones. We divide the listed price by the 18-karat gold weight. The result fits in two characters: €/g. Next to it, we display the day's spot price to show where the listing sits relative to the real market.
One unit, comparable across every site, so you stop wondering whether you're being ripped off.
Eleven stores, one table
Bijouxoccasions, gemme-les-bijoux, adoreshop, 18carats, jolykara, and six others: all tracked continuously. More than two thousand seven hundred active products, refreshed every morning, so you decide in seconds.
